Ridge

Ridge is an anatomical term meaning a narrow, elongated projection on the surface of a bone or other anatomical structure.

In anatomy, ridges serve as attachment sites for muscles, tendons, and ligaments. They increase the surface area of ​​the bone for more secure fixation of soft tissues. Examples of ridges are the frontal crest, the occipital crest, and the supracranial crest.

In dentofacial anatomy, the ridge is understood as the alveolar process of the jaw bone containing the sockets of the teeth (alveoli). After tooth extraction, an alveolar ridge remains, which atrophies over time.

Thus, the crest is an anatomical formation in the form of an elevation on the surface of the bone, which has important structural and functional significance.

A ridge, also known as a ridge, is a long, narrow projection on the surface of a bone or tooth. In anatomy, a crest can be used to represent various structures, such as bone or dental elements. In dentofacial anatomy, the term “ridge” can be used to describe the alveolus, the cavity in the bone where the tooth is located.

In anatomy, the crest can have various functions. For example, it can serve to support and strengthen other bone structures such as muscles and tendons. The ridge can also be used to transfer force and tension from one structure to another.

The ridges can be found on various parts of the body, including the bones of the skull, spine, chest and limbs. They can also be found on teeth, where they serve to support the crown of the tooth and provide stability.

However, it should be noted that the term “ridge” is not always used with the same meaning in anatomy. In some cases, “ridge” may simply refer to protrusions on the surface of a bone that are of no particular importance to its function. Therefore, when using the term “comb”, it is necessary to clarify its meaning in context to avoid confusion and misunderstanding.

A ridge is a two- or multicellular protrusion of tissue. Appears as a narrow, long, ring-shaped elevation of skin, a small ring of hair; located above the brow ridge at the roots of the eyebrow hair. At the base, the curl descends along the neck. In dermatology it is known as molar nevus.

According to ICD-10, the disease code ranges from L83.0 to L85.9. The pathology affects people of all age groups, more often men (compared to the female population), but does not lead to death. The classification is based on the comb options:

* Monolithic: consists of a single cell, the nucleus of cellular material is concentrated in the center of the internal cavity; the element grows vertically and has a cone-shaped shape. There are tubercles on the surface that look like coral. The diameter of the element can reach several centimeters, the pigment appears as redness of the skin. If you comb regrown hair, certain areas are crushed, forming dark stripes that disappear after the regrown hairs fall out. Treatment with medications or surgery does not work. The most effective method is to remove the element with a laser; * Pedzherovsky: characterized by the presence of spines-cuticular cells, which play the role of protective elements. The spines are filled with sclerotic materials. The area becomes keratinized into the skin layer of the dermis, so removal is carried out by shaving; * Marginal: covered with sclerosing papillae. They contain pigment that appears in the form of telangiectasia. The area can disappear or atrophy on its own. The affected area can be removed using medical instruments. As a rule, the effect lasts for a long time, the melanocytic ridge does not grow back;
